Filed Aug. 27, 1959, Ser. No. 836,443 2 Claims. (Cl. 189-44) This invention relates generally to extrusion type construction devices for prefabricated type buildings, and more particularly it pertains to interlocking extrusions for positioning and interlocking construction panels of prefabricated buildings and especially adapted for factory prefabrication and customer erection.

In the prefabricated building industry, it is important to be able to quickly assemble and erect prefabricated parts so as to form a completed building in the minimum of time, with a resulting savings in labor'and material. Most prefabricated building's, especially of ranch type homes, consist of large construction panels which are used to form either the outer shell of the building or the interior walls thereof.

In order to quickly assemble the prefabricated con struction panels, it is necessary to have various arrangements to interlock adjacent panels in an etficient and reliable manner, and in a minimum of time. Additionally, the interlocking arrangements must be'simple, and ones which can be assembled and installed by unskilled labor.

It is, therefore, an object of the present invention to provide interlocking extrusions of various types which can be used effectively and efficiently to position and interlock construction panels used in the fabrication of buildings.

Still another object of this invention is to provide interlocking extrusions of various types which can be used to interlock construction panels either to adjacent panels, flooring, or roofing construction.

And still even another object of this invention is to provide interlocking extrusions of various types for use in building construction which are economical to manufacture, efficient and reliable in operational use, and which are easy to install and maintain;

To provide interlocking extrusions of various types which can be used in sectional panel construction of buildings, such as ranch type homes, is another object of this invention.
